A few other possiblities:
Nekomonogatari(Black). Neko(White) is part of the new season in the Summer so they'd have to do it solo or package deal.
Ryo. Gonzo's Anime Mirai entry. Gonzo and Crunchyroll go way back.
House of Five Leaves. Got a NIS America Standard Edition
Bunny Drop. Has a NIS America Standard Edition and I'd imagine NISA could want it back up.
The World God Only Knows OVAs (could also come in the Summer)
Oreimo OVAs
Some of the TBS shows from previous seasons like Chunnibyou, Tamako Market and Sasami-san@Ganbaranai.
UtaPri Season 1(confirmed).

There could be some others than I am not expecting either. And there is always the chance 1 or 2 of those boxes are live action stuff.
